Can you help me with fft? I don't know exactly how to use it. my goal is to separate the different frequencies.can you share sample code.

I have used NUCLEO-F072RB EVK <==> STUSB4500 and tried to execute below git code.https://github.com/usb-c/STUSB4500/tree/master/FirmwareI received below logs when source device attached:########################################################################=================== USB PD Sink Firmware v1.00 ===================STUSB4500 detected.

If I need to change memory areas in project (for example for Read-only memory I need 0x8080000 start, 0x40000 size), how can I do in in CubeIDE ? (addition) I have found Build analyzer, but the fields are not changeable, only view.

The board was working fine and then after some time i tried to connect again to flash via CUBE IDE but it didn't connect. I am getting the following error when i try to connect using STM32 CUBE PROGRAMMER.i am able to get EVA_H757XI mass storage when i connect the micro USB and also able to upgrade the firmware. I am powering the board using the power brick given along with the board. also attaching the board for your reference. please guide me through in solving this issue. Thanks.

The connections are quite simple Master-CLK , Master->MOSI to Slave->MISO and we only have one Slave so, we aren't using CS. We're only trying to receive simple data but, we're only getting various trash. We have experienced crashing and the clock signal being distorted before but, this went away as soon as we disabled the nss pulse. However, we're still unable to receive useful data. In debug and monitoring the the rxreceive buffer, it's as if there is no connections at all. Just trash. The master clock and mosi signals are doing what we expected though.This is usually a simple fix but, if anyone has insight where we should start looking to fix the issue it would be greatly appreciated!Our test code is below:#include "main.h"/* Private variables ---------------------------------------------------------*/SPI_HandleTypeDef hspi1;/* Private function prototypes -----------------------------------------------*/void SystemClock_Config(void);static void MX_GPIO_Init(void);static void M

Hello everybody!In my company We decided to use ST brand for our "NFC projects". Anyway, now I have Nucleo board 32f070RB and x-nucleo-NFC05a1 with ST25R3911B chip.For now We have a simple project, just to read and write to/from the Tag (some of the classical tags, probably ISO14443A).Unfortunately, there is no official Excample for x-nucleo-05a1 and 32F070RB. For now I just established SPI communication with microcontroller and 25R3911B chip(basic read/ write into a register).Now I need a help because I confused about 2 things and If It's possible to answer me: + What is the steps to Initialize ST25R3911B and start communicate with Tag (I read a datasheet but it's a bit confusing for me)?+ Is it necessary to use rfal and/or st25r3911 libraries or at list which is really necessary?All the best,Domen

In addition neither the datasheet nor the reference manual mention how to access it but the older (pre HAL era) driver versions did support this. The backup registers are even missing in the RTC register map of the reference manual even though these registers are clearly available on all F0 MCUs.

Hallo everyone.I am evaluating this platform and I got it to work with the UDE STK debugger env.unfortunatley when I shutdown my laptop at the end of the day, it seems to loose all the driver settings.The morning after when I try to connect to the boar dit gives me this error message:Message from component 'PpcJtagTargIntf' :Can't connect target !Message from component 'PpcJtagTargIntf' :No JTAG client found !Please check:- target power supply- JTAG cable connection- target configurationI am on W10 Pro x64. I connect the eval board USB cable to the dock (but it has same behavior even if I use the laptop's own ports)The drivers for FTDI and PLS USB JTAG adapter are installed and configured in device manager settings:I don't like having to reinstall the UDE STK 5.0 every day...Has anyone faced the same problem? how did you fix it (if ever)?Thanks in advanceMaurizio

Hi ,all.I wanted to understand where the 16 in this equation comes from, cna anyone epxlain?

I am working on a custom LCD project using STM32h753 Eval 2. Currently i dont have a tremendous knowledge in LCD. I tried to follow the example codes and some tutorial but not able to make it work. can you suggest any resource or steps to get started?i am using a custom 1024*768 LCD. This LCD receives signals through LCDT. the config given by the manufacturer is #define PanelHSyncWidth      43 #define PanelHSyncBackPorch   29 #define PanelVSyncWidth      6 #define PanelVSyncBackPorch   34 #define PanelHStart      (PanelHSyncWidth+PanelHSyncBackPorch) #define PanelVStart      (PanelVSyncWidth+PanelVSyncBackPorch) #define PanelWidth      1024 #define PanelHeight      768 #define PanelHTotal      1344 #define PanelVTotal     &nb

I'm Using the Cube Programmer, I get an Error reading the Location 0x1FFF1E80-8B ( unique MCU ID ) on the STM32H750ZB. I can read the Code memory and connect . correctly.

I am selecting the microcontroller for an application that needs to implement an USB dual virtual com port (composite device with two vcom port). I would like to use the STM32F411 but i see that other people got problems trying to do it, maybe because of the few endpoints of this microcontroller. Can anybody explain me what is the situation?

Hi,I don't want to use the ST25R3916 capacitive card detection that involves CSI and CSO pins. Can I leave this pins unconnected? What part of rfal should I remove to do this?Thanks in advance,gaston

Hi,Where's the ST25R3916-EMVCO documentation? Schematics, BOM, gebers, User Manual.It is an available product? I'm not able to order it through any distributor.regards,gaston

I want to know how to specify the address to load Cortex-M4 firmware when U-Boot or Linux Kernel load the firmware of Cortex-M4 in Retention RAM.​And, how to specify the address to load Cortex-M4 firmware if I load the firmware of Cortex-M4 in Retention RAM and MCUSRAM separately?​In addition, if I load the firmware of Cortex-M4 in Retention RAM and MCUSRAM separately, is the swithing of RetentionRAM and MCUSRAM done by MPU without the programmer being aware of it?

want to exchange large data buffers with the coprocessor.I have done following wiki page.​https://wiki.st.com/stm32mpu-ecosystem-v1/wiki/How_to_exchange_large_data_buffers_with_the_coprocessor_-_example#Source_code​I want to analyze Cortex-M4 source code, So I have get following source code. ​https://github.com/STMicroelectronics/logicanalyser​I want to build the source code, but README says that "Drivers and Middleware are not included in the project; current assumption is that STM32Cube_FW_MP1_V1.2.0RC2 package is located at the same level as the project root folder."​How can I get STM32Cube_FW_MP1_V1.2.0RC2?Or I have to investigate how to build the source code without STM32Cube_FW_MP1_V1.2.0RC2?Best Regards.H.

Hi there!I have a Nucleo F746ZG board that I was going to use to get started with USB programming.I've read every tutorial, every correction suggested to the HAL library (which is, as per usual, full of issues) and absolutely nothing will even get the VCP to show in windows in device manager at all.Here are my steps:STM32CubeIDENew project for the Nucleo.In the device configuration tool:Turn off ethernet:Connectivity->ETH->Mode->Disable (because we aren't using it and it calls Error_Handler which just makes debugging more confusing than necessary.Turn on the USB Middleware:Middleware->USB_DEVICE->Class For FS IP->Communication Device Class (Virtual Port Com)leave everything else as is.Turn on USB_OTG_FS:Connectivity->USB_OTG_FS->Device_OnlyLeave everything else as is.Change clock configuration:Clock Configuration->ensure To USB (MHz) is at 48MHz by whatever means you want to.File->SaveAllow code gen.Upload to device,Plug in user usb cable.Upload again for

HiI am trying to do a simple USART communication via DMA (LL Drivers). I want to send two chars to my STM32F103 from my PC which are received by DMA. In the DMA RX transfer complete callback I want to send some text string, also via DMA back to the sender.For that I wrote extra functions to send the text and to clear the text buffer once the DMA TX has completed the transfer.Receiving the two chars works without problems.Sending text back to the sender also works, but then the DMA1_Channel7_IRQHandler doesn't get called and subsequently all actions that rely on TX Transfer Complete signal don't work anymore, like clearing my TX-text buffer.The buffer for the two receiving chars:char rxBuf[2];configuration of my reception DMA:LL_DMA_SetMemoryAddress(DMA1, LL_DMA_CHANNEL_6, (uint32_t)rxBuf); LL_DMA_SetPeriphAddress(DMA1, LL_DMA_CHANNEL_6, (uint32_t)&USART2->DR); LL_DMA_SetDataLength(DMA1, LL_DMA_CHANNEL_6, 2); LL_DMA_EnableIT_TC(DMA1, LL_DMA_CHANNEL_6); LL_DMA_EnableIT_TE(DMA1, LL
